In the First Volume of this work (pi. 19), the Rhipiphorus 

 paradoxus was figured, an insect nearly related in structure 

 and economy to the one just described. 



The Rhipiphorus inhabits wasps' nests ; the Sitaris we learn 

 from Latreille lives in the nidus of solitary bees, and is often 

 found dead in them. When I was at Lyons last summer, 

 Mons. Foudras, who takes the Sitaris in abundance, informed 

 me that he found it in the nests of AntJiophora hirsiita and 

 A. acervorum. 



Fabricius gives it as an English insect, and it appears to have 

 been common in this country sixty or seventy years back by 

 the remark of Forster, who states that it was frequent upon 

 garden walls; and I think Dr. Stephenson found one in such 

 a situation a few years since at Elthara in Kent. Within the 

 last year or two I understand, it has again been found in 

 abundance under a water-butt in a garden at Chelsea. 



The plant represented is ScropJmlaria vernalis (Yellow Fig- 

 wort), gathered at Mitcham in Surrey, and communicated by 

 J. J. Bennett, Esq.
